Study On The Prediction System For The Ground Movement And Deformation Of The Goaf Based On The Probability Integration Method And The VB Language

Mineral resource is an important pillar of the national economy. The exploitation ofmineral resources broke the equilibrium state of the underground rock. When the destructionof rock mass spread to the surface and caused movement and deformation on the surface, thebuildings, railway and the water on the surface will have a deformation even more aredamaged, which affect human production and living and ecological environment seriously,and constrain economic and social development within the mining area. Therefore, in theexploitation of mineral resources while, the prediction of the movement and deformationdamage on the surface is all the more important after mining.In this paper, the probability integration method, which is verified by a lot of practice atthis stage in China, is used as the main forecasting methods to predict the movement anddeformation of the ground affected by the goaf. The author relies on the VB language toprogram and uses the ground movement and deformation prediction system prepared to carryout the numerical calculation. The methods above can calculate the5surface movement anddeformation predictors of the horizontal, gently inclined and inclined Coal, including thesubsidence value,the curvature value, the tilt value, the horizontal deformation and thehorizontal displacement value in any mining face conditions, and has the ability to generatecontour maps and three-dimensional visualization maps of the subsidence by using surfersoftware to handle the results and generate the main section curves by using grapher software.It provided a scientific basis for predicting the destruction of the environment caused by themining and avoided large errors, inefficient and tedious calculations or other shortcomings inthe manual calculations and hand-drawn maps.The author verified this system designed in the paper can meet the probability integrationmethod calculation in the operational accuracy by comparing the prediction results, andverified that this system designed in the paper has a accurate predictions results by comparingwith the actual monitoring data of the ground movement and deformation destruction. Thesystem can make a better predictions for surface deformation and destruction caused by the mine exploitation.
